The high-end range includes the gearbox lines GSA, GSB, GSF (inline), GSD (flange gear) and GSBL (angle gear). All lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings. The housings are designed from a one-piece, robust housing. This improves the gear rigidity and enables the absorption of higher loads. The sun pinions are fitted with an additional bearing system in order to ensure quieter operating behavior. The 2-stage versions are constructed in a space-optimized design. Due to the lower torque values, the input stage is dimensionally smaller than the output stage.

• Low backlash for highest precision, standard as low as <=3 arcmin, optional as low as <= 1arcmin
• High radial and axial forces permissible
• Simple mounting without intermediate flange

• Low backlash for high precision, standard up to <=3 arcmin, optional up to <= 1arcmin
• High torque level
• Best corrosion protection for complete housing including output side

• High load level due to double bearings
• High torsional rigidity
• Optimum protection against dust particles and water jets

• Compact design
• Highest torsional rigidity
• High permissable radial & axial force

• Right angle version for space restricted applications
• High torque level
• Up to ratio 200 in 2-stage version

The high-end economy lines GSN and GFE are equipped with ground, helical-cut precision components, which ensure low operating noise, very quiet operating characteristics and above-average torque absorption. Both lines have a full needle bearing, which has been especially designed for high torques. The planetary carriers are manufactured as a cage made from solid material. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash.

• Low noise level due to ground helical gearing
• High power density
• Protection class IP65

• Big housing sizes up to 220 mm
• Max. input speed up to 10,000 rpm
• 30,000 h life time

Benefits at a glance:

• Mechanical drive systems for precision portal systems
• Up to 300 m/min process speed
• Positioning and repeat accuracy with less than 1 μm Tolerance
• Based on a modular system

Modern portal systems are engineered for highest precision and highly dynamic contouring. The systems are used for processing flat sheet metal parts, in automated assembly systems or for laser cutting of templates. The modern laser cutting gantries for high-quality processing tasks achieve process speeds of up to 300 m/min and convince with high positioning and repeat accuracy with less than 1 μm tolerance.

In the gantry drive units, rack and pinion drive systems – consisting of planetary gear, pinion and toothed rack – ensure the dynamic and positionally accurate motion sequence.
